Fig. 4From: Quantification of arterial, venous, and cerebrospinal fluid flow dynamics by magnetic resonance imaging under simulated micro-gravity conditions: a prospective cohort studyRepresentative arterial and venous flow rates vs. time over a cardiac cycle for a single subject for the right internal carotid artery and the right internal jugular vein. Negative values indicate flow towards the heart. The explanation for the late location of the systolic peak in this figure is the same as for Fig. 3Back to article page
